How to use
Choose a pattern from the grid and show it on its own. For a newborn, you can hold the display about 20–30 cm (8–12 in) away, move it gently, and watch for your baby’s interest. Reverse the black and white colors or hide the controls as needed. Return to the grid to choose another card.
Viewing time
Keep any viewing brief and follow your baby’s cues. There is no required number of cards, sessions, or minutes.
A few precautions
Stay with your baby and stop if they seem tired, upset, or turn away. Screen viewing should not replace face-to-face interaction and other everyday activities.
